MACHINERY FOR THE MANUFACTURE OF ICE.

Application filed April 19, 1915.

1th all whom it may concern e lrnown that l, THOMAS SHIILEY, of of York, in the county of York and ennsylvania, have invented a new ul lmprovement in Machinery for nufacture of lee, of which the followspecification. invention relates to the can system for making ice, and more particularly to system in which air under pressure is ec'ted into the body of water in the can at or near the bottom to prevent impurities in t' e water from being incorporated in the ice d1 ing th freezing operation.

it has to do more particularly with the construction and arrangement and fitting together oi the can and the tube through which air injected into the interior of the the cbiect being primarily to reduce the cost manufacture, and furthermore to b '"1 an. etl'ective and easily manipulated of the can and tube, and one which permit the ready repair or replacement tube whenever desired.

connection with the accompanying drawand will then point out more specifi- ,he claims those features of the same believe to be new and of my own ntion.

drawings-Figure 1. is a view of ith the air tube applied; Fig. 2 is vertical section through the air t of the can on line 2-2, Fig. 1; is an enlarged cross section on line 9 AL 21. he can. shown at A. It is made of snootmetal as usual, and can be of any convenient or preferred construction and sh 3--of rectangular cross section in the pres nt instance.

is the wrought iron reinforcing band at top oi: the can. in one ot the longer sides of the can 1s Jr, he

\ termed the external vertical groove 0 of ap cross section which extends from the top of the can to near the bottom of the same. A hole in the lower end of groove opens into the interior of the This construction permits of the use of a straight length of air tube, only the lower portion of which extends into the can.

is the air tube. It is inserted in the rove "C from the top of the can, between the baz-ulll and the grooved side of the can,

groove C through the hole 7 in the lower end of the same into the inside of the can until its beveled lower end at is near enough to the bottom of the can to secure proper cir' culation of the air discharged from it. In the drawing the beveled end is shown as reaching to the can bottom, but this is not necessary. The portion of the air tube D which is held in place by the band B is cylindrical, and is reamed out on a taper to receive the air nozzle (indicated in dotted lines, Fig. 2). Below this point the tube is preferably somewhat flattened on its eX- posed side, as seen at 0, so that it shall not materially project beyond the side of the can. The depth of the groove C relatively to the dimensions of the tube preferably should be such that when the tube is seated therein the external flat side c of the tube shall be practically flush with the outside of the can, the tube in this way being shielded and protected from accidental injury in handling the can.

The beveled end (Z of the tube D is the only air nozzle needed. Air discharged from that end will be forced toward the vertical center line of the can.

The hole ,1" in the lower end of the groove C is of shape and size to closely fit the tube D which passes through it and the tube and side of the can are soldered together at this point to make a tight joint. This is the only point where soldering between the can and air tube is required, the tube, held in place above by suitable means-in this instance by the wrought iron band B-being free to expand and contract without liability of being loosened, distorted or thrown out of place. The tube and can may also be united, by solder if. desired, at other points between the lower end of the groove C and the top of the can, but this is not indispensable.

The groove C in the present instance is located on the center line of the can side.

It is on this line that the blocks of ice are shape, however,

bottom, in combination while desirable, is not in dispensable. The tube may be cylindrical throughout, or of any other preferred cross in the exterior of the can should be of such depth relatively to the dimensions of the tube as to' bring the latter Within the plane of the face of the can in which it is seated. But this also is not indispensable; the depth of the groove may be such that the tube, while seated 'in it, may project to some extent from it. What is esse groove C in the side of b from the top of the can part Way only to the. with the air tube seated in the groove and extending through the lower end'of the same down into the, interior of the can, and

the cam-the only solder or other tight joint at the point f where the tube passes through the lower end of the groove C from the outside'down into the inside of the can.

aving described my improvement, what I claim as new anddesire to secure by Letters Patent iS 1. A, freezing can having in one of its sides an external grooveext'ending from its top-partway to Its bottom, 1n combination Wit an an tube seated in said external groove wlth its loWer portion extending on the prolongation of the upper portion straight down through the end wall of said groove into the interior of the can and making awater tight joint with the can at that point, and means for holding the air tube in top to near its ,tially as and making a water tlght joint with the can at the purposes hereinbefore set forth.

' freezing can having in one of its sides an external groove extending from its top to near its bottom, in combination with an air tube seated in said groove, said tube having a cylindrical upper end and, below that point, being flattened onits exposed side to be substantially flush with the extorior of the can, the lower end of the tube projecting on the prolongation of the external portion of the tube straight down through the end Wall of said groove into the interior of thecan and making a tight joint with the can at that point, andmcans to conine the tube in place in the groove, substanfor the purposes hereinbefore set forth.

v, In testimony whereof I afiix my signature.
